Yes, there are two levels of upgrade:

"Soft upgrade" (database format remains at 10.2 level, so you can still use 
10.2, and use 10.3 with some limitations)


"Hard upgrade" (database format is upgraded, so there is no turning back to 10.2 
after upgrade, but you get to use all the new features of 10.3).
